Anti-Resonant Hollow Core Fibers

Optical signal in hollow core anti-resonant fibers propagates in an air core surrounded by single ring of anti-resonant tube elements. Guidance is based on an anti-resonance from the thin glass membranes constituted by the non-touching tubes surrounding the hollow core. The extremely low overlap of guided power with the surrounding silica, less than 2x10-5, added to the mode effective area, confers to these fibers design record material non-linearity.

Product features：High damage threshold、 Nearly single mode guidance、 Ultra low dispersion in the transmission bands

Application area：Low latency data transmission、 Gas-filled AR hollow core fibre laser、 Molecular tracing, gas detection、 High power delivery for pico- and sub-picoseconds、 optical pulses

A hollow core fibre adapter is designed to connect hollow core fibres with single-mode fibres. Featuring a modular packaging design, the adapter enables optical power coupling between hollow core fibres and single-mode fibres with low insertion loss and low return loss. It allows for direct connection of hollow core fibres to existing transmission systems, enhancing user convenience. Furthermore, when used in conjunction with hollow core fibre cables, the adapter contributes to the construction of a complete low-latency communication system.
